Neurogenic tumors located in the posterior mediastinum, generally require surgery which be confronted with greater risk,therefore, to design the best surgical approach and surgical methods is essential. A 67-year-old female patient had pharyngeal foreign body sensation and dysphagia. Thyroid ultrasound showed the right thyroid had a little nodule, and the left thyroid had a hypoechoic lumps. Neck enhanced CT showd mediastinal mass, esophageal tumor origin or stromal tumor? We used the jugular approach to resect the tumor which eventually diagnosed as schwannoma. The meditational benign tumor with an envelope easy to peel can employ the jugular approach to resect it completely.

DiGeorge syndrome is an immunodeficient disease associated with abnormal development of 3rd and 4th pharyngeal pouches. As a hemizygous deletion of chromosome 22q11.2 occurs, various clinical phenotypes are shown with a broad spectrum. Conotruncal cardiac anomalies, hypoplastic thymus, and hypocalcemia are the classic triad of DiGeorge syndrome. As this syndrome is characterized by hypoplastic or aplastic thymus, there are missing thymic shadow on their plain chest x-ray. Immunodeficient patients are traditionally known to be at an increased risk for malignancy, especially lymphoma. We experienced a 7-year-old DiGeorge syndrome patient with mediastinal mass shadow on her plain chest x-ray. She visited Severance Children's Hospital hospital with recurrent pneumonia, and throughout her repeated chest x-ray, there was a mass like shadow on anterior mediastinal area. We did full evaluation including chest computed tomography, chest ultrasonography, and chest magnetic resonance imaging. To rule out malignancy, video assisted thoracoscopic surgery was done. Final diagnosis of the mass which was thought to be malignancy, was lymphoproliferative lesion.

Thoracic duct cysts in the upper portion of the diaphragm are mostly found in the neck and are rarely found in the mediastinum. Thoracic duct cysts should be differentiated from other mediastinal tumors or cysts, and surgical treatment is required to avoid the development of chylothorax if the cyst ruptures. Herein, we report the case of a patient with a thoracic cyst located just above the diaphragm that was treated with surgical resection.

Mediastinal paragangliomas are very rare neuroendocrine tumors. Complete resection is the standard treatment of a paraganglioma because of the tumor's potential malignancy and poor response to chemo- or radiotherapy. However, the highly vascular nature of the tumor and its characteristic anatomic location make complete resection difficult. We report a case of an anterior mediastinal paraganglioma, which was incidentally found on a chest computed tomography scan for chronic cough work-up of a 55-year-old woman. Complete resection was accomplished using video-assisted thoracoscopic surgery, and the patient recovered without any complications.

Myelolipoma in the mediastinum is an extremely rare entity. In this report, we present the case of a 79-year-old asymptomatic man who had three bilateral paravertebral mediastinal tumors. The three tumors were resected simultaneously using bilateral three-port video-assisted thoracoscopic surgery (VATS). There has been no evidence of recurrence within four years after the operation. Multiple bilateral mediastinal myelolipomas are extremely rare. There are no reports in the English literature of multiple bilateral thoracic myelolipomas that were resected simultaneously using bilateral VATS. We also present characteristic features of myelolipomas, which are helpful for diagnosis.

Mediastinal teratomas have been reported to mimic pleural effusions on chest radiography. Further evaluation of such tumours using computed tomography usually yields diagnostic characteristics that distinguish them from pleural collections. We report a patient with a mediastinal teratoma that mimicked a massive left pleural effusion on chest radiography and computed tomography.
